Compression Spring Tech Info

Learn all you need to know about compression springs amongst other spring types like barrel, conical, and dual-pitch springs. You can find from design and technical information, to knowing more about our website and how our tools will work for you. Click on a title to learn more about the subject.

Compression Springs

Compression springs are helically wound wires with pitch in between each coil in order to store and release force/energy when compressed and released. They are made to have memory so once a load/force is released, they will return to their original length.


Spring Load & Rate

Load and rate can be confused and, although one is derived from the other, they are completely different things. Rate is the force of your spring measured from 1" of travel while load is the actual working load you'll be using to make your spring deflect to a specific loaded height.


Compression Spring Dimension Measurements

A compression spring dimension is the measurement of the elements that make up your compression spring. To buy compression springs online, any type of compression spring, you must know your spring’s dimensions.


Conical Tapered Spring Dimension Measurements

A conical spring dimension is the measurement of the elements that make up your tapered spring. To buy conical tapered springs online, any type of compression spring, you must know your spring’s specifications.


Which Type of Spring is Needed for My Application?

Learn which type of spring is best for your application and how each of those spring types work. Compression, Extension, Torsion...


Constant Force Spring

What makes a compression spring a constant force spring? Constant force compression springs are linear springs who's force is proportional to the amount of travel it is required to compress.


Coil Spring Solid Height

The height of a spring when it is fully compressed and all of its coils are touching one another. At this point no more force/energy can be gathered by the spring.


Spring Compression Formula

Learn the formula to calculate your compression spring’s deflection and how to manipulate the force of your spiring by adjusting the physical dimensions.


4 Compression Spring Design Problems

Compression spring design problems and solutions. Tips to improve your design and avoid common issues.


Springs In Parallel

When a group of springs work together under one force or load. Discover the formulas and equations to calculate the equivalent spring rate.


Helical Spring Rate

A helical compression spring is a mechanical object made of wire which is wound to form coils. They are used to absorb shock, maintain a force between two objects, and to absorb and release energy.


Helical Spring Formulas And Equations

The formulas and calculations required to work on a coil compression spring design. Find formulas for calculations of physical dimensions, working loads and deflection.


Counting Coils - Active and Inactive

Learn how to differentiate active coils from total coils. Total coils represent all the coils that make up your spring design. Active coils are the open wound coils that carry the load and deflecting under it.


Stainless Steel Helical Springs

Find stock and custom helical springs made of stainless steel. In our stock compression spring catalog, you can select from over 6,500 stainless steel springs.


Compression Spring Max Deflection

Load and travel are relative to each other based on the spring rate. Learn how the elastic limit works to understand your compression spring’s travel/deflection.


Spring Index

Spring index is the proportion between the wire diameter and coil diameter (how tight the coils are). It can help determine key characteristics of a coil spring and affects its manufacturing.


Top 3 Metal Spring Materials

There are different materials used in metal spring manufacturing. The three most common are: music wire, stainless steel, and chrome silicon. Consider the properties of each material.


Plating And Surface Treatment Options

There are several reasons to why a spring might need plating. We have provided the properties of the most common plating and finish types we offer.


What is a Compression Spring?

Compression springs are helically coiled, open-wound springs. These springs have pitch between each coil and are meant to be compressed.


Compressing A Compression Spring

Compression springs have the ability to absorb the force placed on them as they compress, and then return to its original form when the load is removed.


The Slenderness Ratio Is Making Your Spring Buckle

Bending or buckling causes the spring to wobble as it compresses and creates instability and lack of proper performance. Learn how to improve or avoid it.


3 Industries That Use Compression Springs

Coil compression springs have been around for a long time but different industries have used them to create and innovate their applications. Learn more about them here.
